Pediction method of rock stratum anti-diamond characteristics of carbonate rocks used in Qinghai YingXi block
PetroChina Research Institute of Petroleum Exploration & Development, Beijing 100083, China
At present domestic drillability prediction is mainly aimed at sandy mudstone formation, The aim is to study less carbonate strata. With the increase of carbonate exploration reserves, the development of carbonate is the main task facing oil companies. This paper has passed the indoor core test, combined with site logging data, research and analysis of mathematical statistics. The relationship between the rock drillability, compressive strength and acoustic jet lag, plasticity coefficient and poisson ratio, and the difference between the surface acoustic jet lag and the time difference between the wave jet and the wave jet were also found. A prediction model is established for predicting the parameters of drilling resistance in carbonate rocks using well logging data. In this paper, the anti-drilling characteristics of carbonate rocks in Yingxi block of Qinghai oilfield are analyzed, Provide reasonable basis for the selection of bit type in the area.
