On June 10. 2016, By my company independent research of the clean   steering acid in Northeast Bureau o YP13 well application is successful. First open well gas production  130000 square, since 2014 this is the first time for YS1 well  successful application, the other four Wells, on average, the growing volume of 133000 square, valid for more than 1 year, for Northeast Bureau to create the good economic benefits.

The volcanic rock reservoir in Northeast Bureau with deep buried depth, high temperature reservoir, cracks, holes are developed, reservoir thickness and permeability of non reservoir characteristics.  The drilling fluid and completion fluid leakage serious, great pollution of the reservoir, the production yield is low or even no yield, the  conventional acidizing are acid fast response, action radius small, acid to local breakthrough problem.

Company and the Northeast Bureau Engineering Institute of technical research together, successfully developed a clean auto steering acid fluid system, with acid gelling performance, can delay the reaction rate of acid liquid, also rely on with special rheological properties of diverting agent. In different conditions to achieve acid liquid layer automatic steering, for achieving long well segment uniform transformation, restore or increase oil and gas production. And with surface tension is low, the characteristics of gel breaking, no residue, no pollution on the production layer, can effectively solve the long segment of no homogeneous reservoir acidification problems.
