The application instance of wireline coring technique was introduced with the project case of coal-bed methane parameter well in Baotian-Qingshan area of Guizhou,the drilling techniques were brought forward in accordance with complex formation,unstable borehole wall,being hard to core in coal powder.

Aimed at general situation of CBM in Qinshui Basin,strata condition and exploitation condition,introduced parameter well,producing well,multi-bran chsurface CBM horizontal development well and cluster wells drilling technology,drilling tool assemblage,well structure and well quality requirements.

Coal bed gas parameter well SPMT-1 is located at the Shiping well field, Guxu mining area, South Sichuan Coal Field.

Inversion of multi-logging parameters under constrain of relative wave impedance data volume and application.;

In the past, the prediction of the reservoir production capacity by logging parameters was based on a single testing well.

The causes producing logging parameters and containing water of the low resistance reservoir are analyzed.

, drilling parameters reasonably matched well, polymer clay free drilling fluid injected-time prolonged, drilling bit types .

Based on principle of modularized design,the article discusses how to divide modules of drilling parameters instrument,rules of design and the main work of design.

Starting from the view point of practical application, based on large amount of pressure well logging data home and abroad, the author demonstrated how to distinguish over-pressure formations using wellsite data, through selected methods such as drilling parameters, rock fragment analysis, drilling fluid parameters, and electric well-logging.

In weakly consolidated formations,the technical challenges of drilling a horizontal well include lower rate of overall inclination change,improper MWD signal transfer,difficult to select drilling parameters and bottom hole assembly,etc.

It is the priority to develop the design of numerical drilling system information source,including drilling parameter,production,and management parameters.

Most conventional anti-deviation devices have inherent limitations, and their anti-deviation effects are greatly affected by drilling parameters such as bit weight and rotary speed.

The signature recognition of comprehensive logging parameters in sedimentary microfacies of clastic reservoirs.;

The optimum DSM logging parameters are summarized through a large number of logging practices in order to conlribute to the application and popularization.

, the authors expound that, as a method of nonlinear inversion, Seimpar Inversion could carry out wave impedance inversion without using convolution equation, and also inverse logging parameter by seismic records under the logging constrained.

The geological logging in Xihu Trough makes it clear that the lithology has close relation to the curve change of torque and the rate of top drive, and it is important to apply these logging parameters in order to establish the lithology section fast, to discover the oil and .
