Shaanxi cementing material introduction cementing

In order to ensure that in the process of underground exploration, to ensure continued safe drilling, to seal off the oil, gas and 

water layer to strengthen the well wall,to ensure the stratified testing during exploration and reasonable oil and gas production

 during the entire mining process and other purposes of the production ofhigh-quality steel pipes, and in the wellbore and steel

 pipe annulus filled with good cement operations, known as cementing engineering. So what is the purpose of cementing? Next, 

Shaanxi cementing materials to talk about the importance of cementing engineering

Shaanxi cementing material Introduction The importance of cementing:

1. Seal off complex formations prone to collapse and leakage, consolidate drilled holes and ensure smooth drilling;

2. Provide the basis for installing the wellhead device, control the wellhead spray and ensure that the mud outlet in the well is higher 

than the mud pool to facilitate the flow of drilling fluid back to the mud pool;

3. Seal off oil, gas and water layers to prevent oil, gas and water layers of different pressures from channeling each other, providing

 favorable conditions for normal oil and gas exploitation;

4. Protect the fresh water resources in the upper sand layer from the pollution of oil, gas, salt water and other liquids in the lower

 rock layer;

5. After the oil well is put into operation, favorable conditions are created for acidizing and fracturing stimulation measures;
