Cabrera-Bello, who played 30 holes on Friday completed the first round in 67 and then added a three-under-par 69 to take the clubhouse lead at eight-under 136, despite two bogeys in closing three holes.
Kapur was one of the four players who had completed 36 holes and totalled seven-under 137.
Thailand's Kiradech Aphibarnrat and Kapur were trailing close behind by one shot, while Jeev was also at seven-under, one behind the leader, but he still had seven holes to play in second round, which he will complete on Saturday morning.
Also at seven-under and with seven holes to play like Jeev was Thongchai Jaidee of Thailand.
The Spaniard dropped two shots in his closing three holes but still managed to retain his advantage with a two-day total of eight-under-par 136 at the DLF Golf and Country Club.
Kiradech and Kapur were alongside England's Robert Coles and Denmark's Mark F Haastrup in tied second at 137 in the event -- tri-sanctioned by the Asian Tour, European Tour and the Professional Golf Tour of India (PGTI).
Spaniard Cabrera-Bello starting on the tenth birdied his opening hole before sinking a 30-feet putt for another birdie on the following par-three 11th. He continued to birdie the 15th, 16th and sixth holes before committing bogeys on holes seven and nine.
"Eight under after two rounds and leading in the clubhouse so I've to be happy," said Cabrera-Bello who has won once on the European Tour.
"I''m playing well but this is a very weird sport and you have to try to focus day-by-day and shot-by-shot and if I'm in with a chance on Sunday I'll try to take it," added the Spaniard.
Kapur who started his round tied for 44th made one of the biggest moves of the day and quickly credited his coach for turning his game around on a day when he played 27 holes, nine from the first and 18 in the second.
"The 30-minute break between the finish of the first round and the start of the second round did a world of good. I spend some time with my coach (Jamie Gough) and we found something that helped me through the second round," said Kapur, who had a flawless round that was highlighted by seven birdies.
"After that small session with Jamie, things came together. I hit a lot of good shots and good putts, which came close or shaved the hole. There were no putts that didn't have a chance. I could easily have been 10 or 11 under, but I suppose that can be said for everyone if all their putts fall too," added Kapur.
