The Research of Microparticle Filling Agent in Protecting Hydrocarbon Reservoir Technology

Article Preview

Abstract:

In order to protect carboniferous system layer in east Sichuan, it added microparticle filling agent in drilling fluid. It depended on the physical truth and principle of protecting hydrocarbon reservoir technology which used in drilling fluid. According to the property of filling agent, it studied fluid loss control agent CKH-1, calcium carbonate superfine powder, non-permeate pressure-bearing agent CY-1 and nanometer material. Dosage of CKH-1 was 1%, calcium carbonate superfine powder was 2%, CY-1 was 4% and nanometer material was 1% ,which were firmed via experiment of viscosity and fluid loss control. Microparticle filling agent was sequentially formed.
