提高复杂断块油藏开发效益

Increasing the Development Comprehensive Benefit of Complicated Fault-Block Oilfield

以文留复杂断群油藏为例,对特殊钻井和下φ101 6mm套管重新完井技术在不同类型、不同开发阶段中的应用进行了归纳分类,认为特殊钻井技术和完井新技术对改善油田开发效果、提高开发综合经济效益发挥了独到的作用,并进行了技术经济评价、指出特殊钻井技术是复杂断块油田经济高效开发的主导,下φ101 6mm套管重新完井技术是解决井况恶化和实现层系细分开发的有效途径。

This paper takes Wenliu complicated fault block oilfield as an example,classifies and induces the applying situation of special drilling and 4 inch casing completion in 512 inch or 7 inch tube well technology used in various reservoirs and different development stages. The research result is that special drilling and new well completion technology has distinctive effect on improving oilfield development and increasing the development comprehensive economic benefits. At the same time, the following viewpoint can be obtained that special drilling technology is the dominant drilling technology for making complicated fault block oilfield’s economic and high effective development,4 inch casing completion in 512inch or 7 inch tube well technology is an effective way of removal casing worsen and realizing the subdivided development of series of strata.
