초록 ▼

A technique is provided to facilitate perforation operations in a well. A well treatment operation is combined with a perforating operation to increase the efficiency of well preparation. A dart assembly has a dart for moving a well treatment fluid downhole and a perforating gun coupled to the dart. As the dart moves the well treatment fluid to a desired region of the well, the perforating gun is simultaneously moved to a desired location for perforation of the well.

What is claimed is: 1. A perforating system, comprising: a cement dart sized for movement downhole through a casing; a perforating gun coupled to the cement dart for movement with the cement dart as a single assembly, the cement dart leading the perforating gun to enable displacement of cement; and a firing head coupled to the perforating gun. 2. The perforating system as recited in claim 1, further comprising a spacer between the perforating gun and the cement dart to locate the perforating gun at a specific location once the cement dart is landed downhole. 3. The perforating system as recited in claim 1, wherein the cement dart comprises a scraper to scrape cement from an inside surface of the casing as the cement dart is moved downhole. 4. A method of perforating, comprising: connecting a perforating gun with a firing head to a dart sized for movement downhole through a casing such that the dart leads the perforating gun during the movement downhole to enable displacement of cement; and delivering the dart and the perforating gun to a desired location in a wellbore. 5. The method as recited in claim 4, further comprising moving a treatment fluid into the wellbore ahead of the dart as the dart is moved downhole. 6. The method as recited in claim 4, further comprising moving a cement sluffy into the wellbore ahead of the dart as the dart is moved downhole. 7. The method as recited in claim 4, further comprising coupling a firing head to the perforating gun prior to delivering the dart and the perforating gun to the desired location. 8. The method as recited in claim 7, further comprising spacing the perforating gun from the dart with a spacer. 9. The method as recited in claim 4, further comprising utilizing the dart to scrape an inside surface of the casing as the dart and the perforating gun are delivered to the desired location. 10. The method as recited in claim 4, further comprising firing the perforating gun and creating perforations at the desired location. 11. The method as recited in claim 4, further comprising measuring the distance the perforating gun and the dart travel downhole with a deployment mechanism. 12. The method as recited in claim 4, further comprising measuring the distance the perforating gun and the dart travel downhole. 13. A method of perforating, comprising: moving in combination a cement dart, a perforating gun and a firing head downhole as a unit; delivering a cement sluffy downhole with the cement dart; waiting for the cement sluffy to cure downhole; and firing the perforating gun to create perforations at a desired location. 14. The method as recited in claim 13, further comprising inserting at least one spacer between the cement dart and the perforating gun. 15. The method as recited in claim 13, further comprising scraping an inside surface of a tubing with the cement dart as the unit is moved downhole. 16. The method as recited in claim 13, further comprising landing the cement dart in a casing shoe. 17. A system, comprising: a well treatment system having a tubing through which a treatment fluid is moved; and a dart assembly movable through the tubing to a desired location, the dart assembly comprising a dart coupled to a perforating gun to form a combined assembly with the dart leading the perforating gun to move the treatment fluid ahead of the perforating gun. 18. The system as recited in claim 17, wherein the dart assembly further comprises a firing head coupled to the perforating gun to fire the perforating gun. 19. The system as recited in claim 17, wherein the dart is a cement dart. 20. The system as recited in claim 17, wherein the dart comprises a scraper to scrape an inside surface of the tubing as the dart moves through the tubing. 21. The system as recited in claim 17, wherein the dart assembly comprises a spacer having a desired length to space the perforating gun from the dart. 22. The system as recited in claim 17, wherein the well treatment system comprises a landing member to land the dart at a desired location. 23. The system as recited in claim 17, wherein the well treatment system comprises a cementing completion.
