页岩气水平井钻井液技术的难点及其选用原则

Difficulties in Drilling Fluid Technology of Shale Gas Horizontal Well and Its Selection Principle

我国科学技术的不断发展,页岩气成为当下非常重要的潜在能源,尽管其存在的形态多种多样,但是在主体的形式上其性质应该是一种天然气,以甲烷的方式存在。在对页岩气的利用过程中,其以高效、清洁的优势深受人们的喜爱,同时气层又和常规的能源之间有着一些差异,这些差异的存在对气流阻力和渗透率都有影响,所以也给开发的过程一些难度。

The continuous development of science and technology in China, shale gas has become a very important potential energy, although its existence in a variety of forms, but in the form of the main form of its nature should be a natural gas, the existence of methane and the formation of The In the process of using shale gas, it is well received by people with high efficiency and cleanliness, and there are some differences between gas and conventional energy.The presence of these differences has an impact on airflow resistance and permeability, So it is also some difficulty in the development process.
